Cheapest brand new bundle I can find for my kids for christmas at 219, not a refurb or an ebay outlet, but collect at store from Comet. Amazon = £245.
Includes the Xbox 360 and Kinect Sensor and kinect adventures. Cheapest elsewhere I could find was £240 and its £245 at Amazon - http://www.amazon.co.uk/Console-Drive-Kinect-Sensor-Adventures/dp/B003UTUBRA
+ 3% Quidco = Cashback of £6.57 meaning this actually cost you £212.43!!! (thanks MinstrelMan)
